' ADJUSTABLE ASE.-

A pplication filed-March 14, 1927. Serial No. 175,151

My invention relates to adjustable bases for floor lamps, smokingstands, coffee tables and the like, andparticularly to bases having anadjustable framework adapted to have superimposed thereon and to'haverigidly held therein a slab of onyx, marble or similar Ornamentalmember.

In floor lamps, smoking stands, andthe like, making use of suchornamental members as part of the bases thereof, it is necessary anddesirable to have a. framework to hold such ornamental member in pl.ace,sup port same above the floor and also to support the upright standardor standards of the lamp, smoking stand or similar article in whichsuchbase is made use of. An ob ject of the invention is, therefore, toprovide a neat, simple, ornamental and ineXpen siv e framework for thispurpose. I

Another objectof the invention is to provide means on said baseframework for readily adjustingsame to fit the particularj'size andshape of the ornamental member superimposed on said framework. Inpractice, it very diflicult to produce onyx. marble or similarornamental substances in slabs of precisely uniform size and it is notunusual to find the slabsvarying slightly in size and shape, sothatwhere a non-adjustable base framework is used, the ornamental member isvnot held rigidly in place, the fit is not a curate and the job asv awhole is unsatis factory. \Vith applicants device, however, a. perfectlit is produced in' every instance, since the frai'nework'is accuratelyadjusted to the particular size and shape of the slab held therein, andit is possible to form integral with the legs of the framework laterallyextending ornamental fingers, which lie adjacent the edges of theornamental slab and serve as clamping members to hold the slab rigidlyin place, as well as serving for additional ornamentation. This featurehas hitherto been impracticable due to the variance in size and shape ofthe slabs used, the expense of machining, etc.

Other objects and features of the inven- Lion will appear from thefollowing description and drawing illustrating an embodiment of theinvention, merely for the purpose of affording an understanding of theinvention and not forlimitation thereof.

In said drawing, Fig. 1 is a perspective VlOW of an adjustable base ofmy invention, adapted for a smoking stand, floorlamp and the like. Fig.2 is a cross-sectional view of p irt of the base, showingthe mode ofattachment of the leg members to the base on the line 33, Fig. 2.

,The device comprises a spider frame or plate 10, havingradialextensions or arms 12. 12 and leg members 14, 14 adjustably attached tosaid arms 12, the device being supported a short distance above thetloorby downward extensionsl6, 16 on leg members 14, 14. A slab of onyx,marble or similar ornamental member 18, indicated, in dotted lines inFig. 1, is adapted to be superimposed on the device and be rigidly heldin place thereon between the upward extensions or fingers 20, 20 on legmembers 14, 14.

To accommodate the device to ornamental members of varying sizes andshapes, means are provided for making the leg members 14 adjustablewith'respect to the arms 12. Said arms 12 are provided in their uppersurfaces frame, and Fig. 3 is a cross-sectional view with grooves orchannels 22, preferably ta per-sided, extending longitudinally thereof,and in said channels 22 and extending in the same direction therewithare elongated slots 24. The leg members 14 are provided on their undersides with longitudinal ribs or tongues 26, also preferably taper-sided,adapted to register with. and slide in the channels 22 of arms12. Inthis way there isobviatedthe possibility of side-play between thelegmembers 14 and the arms 12, and there is a tight fit of the one in theother in any adjusted position. Any fastening means, such as screws 28,may be passed through the 'apei'turesfiO' provided in the leg members14, and through the elongated slots.

24 in the arms 12, to hold the two together in any adjusted position. Toprovide greater adjustability betweenv the leg members 14 and the arms12, additional apertures may be provided in the leg members 14, such as31. 31.

Plate 10 is provided with a tapped aperture 32 in its center, to receivethe upright standard of the floor lamp, smoking stand or other articleof which the base forms a part, which upright standard passes through anaperture in the center of the ornamental member 18, and is screwed intosaid aperture 32.

The arms 12 on plate 10 may be of any size or shape, and although foursuch arms are shown in. Fig. 1, it is to be understood ornamental designand may be of an that a greater or lesser number may be used, ifdesired, depending on the size and sha of the ornamental member adaptedto e superimposed on the device, and depending also onthe ornamentalefl'ects desired to be obtained.

The upwardly extending fingers 20 on the leg members 14, which liecloselyadjacent the edges of the ornamental member 18 and serve to holdsame I'i idly in place on the device, may be of any esirable size orshape required to harmonize wit' the ornamental member 18 and with otherparts of the article of which the'base forms a part. 7

To assemble the base, the leg members 14 are loosely screwed to the arms12 of the plate 10. The slab 18 is placed on the framework 10 and theleg members 1e drawn up closely against the edges of slab 18 sothat theupwardly extending fingers 20 of the leg members 14 tightly clamp theslab 18, and then the screws 28 are tightened. The base when soassembled makes a perfect fit and presents a pleasant appearance, andthere is no play of any kind.

between the parts.

In one-piece base frames now in common use, it is necessary to gild orplate the entire device, although but a few small parts are visible tothe eye when the base is actually assembled on an article, such as afloor lamp, smoking stand or the like. With a plicants device, however,there is a su stantial saving in this direction, since the only parts ofthe base framework visible to the eye being a few small parts of the legmembers, it is only necessary to plate or gild the leg members 14. V 1

Vith applicants construction, the parts can be made in a simple castingoperation much quicker and at substantially lower 1 prices as comparedto base framework constructions now in common use. The device is easy toassemble and take down, it has the desired adjustability to enable eacharticle turned out to be accurately assembled and fitted, and alltheornamental slabs can be made use of without any waste, re-

gar'dless of slight variations in size or shape, and thedevioe enables ahigher degree of ornamentation tobelseoured.

Changes and modifications may be resorted to within the scope of myclaims, without departing from my invention.

I claim:

1. A base frame of the class described, comprising a central plateprovided with radially extending arms hav ng longitudinally extendingrooves at their upper sides longitudinally: extending grooveswithinclined walls opening along the upper sides of the arms and withelongated slots formed in the bottom wall of said grooves, legs providedwith lon itudinally extending tongues with inclined walls adapted to beslidably received in said grooves, fastening members extending throu bsaid slots and engaging said legs to hol and clamp same rigidly inadjusted"position with respect to said arms, and upward and downwardextensionson the leg members the latter serving as feet to sup ort theframe and members carried there y and the former serving to engage ablock or other member supported upon the leg members and to clamp same1n place when the leg members are forced inwardly toward the centralplate and fastened in such relation.

In testimony whereof I have signed my name hereto.
